Heli-Coil® screw thread inserts
Types of Inserts
There are two styles of
Heli-Coil inserts. The
STANDARD or Free Running
Insert – available in both
Tanged and Tangless – which
provides a smooth free-running
thread; and SCREW-LOCK –
available in both Tanged and
Tangless – which provides selflocking torque on the male
member by a series of “chords”
on one or more of the insert
coils. They are available in inch
series, coarse and fine and
metric series, coarse and fine.
Inch series Screw-Lock inserts
are dyed red for identification.
Heli-Coil inserts are precision
formed coils of extremely hard,
diamond shaped 304 stainless
steel. When installed into an
STI tapped hole, they provide
permanent conventional 60°
internal screw threads. This
assembled insert accommodates
any standard bolt or screw as
per MIL-S-7742 and AS8879
(UNJ controlled root radius). See
page 9 for material availability.
Heli-Coil inserts are larger in
diameter before installation
than the tapped hole. During
installation the inserting tool
applies torque to the tang
reducing the diameter of the
leading coil permitting it to
enter the tapped thread. After
installation, each high tensile
coil of the insert expands
outward with a spring-like
action permanently anchoring
the insert.

positive means for protecting and
strengthening tapped threads in any
material. The unique design features
of the insert offer many benefits.
UÊ -ÌÀ}iÀÊÃÃiLiÃ°
Tapped threads are strengthened
because the inherent flexibility
of the insert provides a more
balanced distribution of dynamic
and static loads throughout the
length of thread engagement.
This flexibility also compensates
for variation in lead and angle
error allowing each coil to carry
its share of the load.
UÊ
Ê/Ài>`Ê7i>À°
Thread life is dramatically
increased even after repeated
assembly and disassembly
because the insert hardness
and surface finish practically
eliminate erosion of the
thread form due to friction.
UÊ ÀÀÃÊ,iÃÃÌ>Vi°
Under normal environmental
conditions, Heli-Coil inserts
minimize galvanic action
within the threaded assembly
because of their superior
corrosion resistance.
UÊ iÃ}ÊiÝLÌÞ°
Bolt tensile strength can be
balanced against parent material
shear strength, assuring bolt
failure rather than parent
material damage. Five insert
lengths are available in each
thread size.
place – the outward spring-like
action of the insert holds it in
place.
UÊ âiÊ-«>ViÊEÊ7i}Ì°
Heli-Coil inserts allow use of
smaller bosses, flanges and
fasteners than any other insert.
Heli-Coil inserts can generally
be incorporated in existing
designs, where no provision
has been made for an insert,
without increasing boss size.
UÊ âiÊ/Ì>Ê
ÃÌ°
Cost savings abound. Lower
insert cost, lower installation
cost and Heli-Coil inserts
provide design flexibility by
allowing a wide choice of
parent materials while
maintaining maximum
threaded assembly strength.
UÊ /ÀÕiÊ
>«}Ê/ÀµÕi°
Maximum clamping action and
bolt tension are assured with
minimum wrench torque because
of the mirror-smooth surface
finish of Heli-Coil inserts.
UÊ 7ìÊ/i«iÀ>ÌÕÀiÊ,>}i°
Heli-Coil stainless steel inserts
can be used in temperatures
ranging from –320°F to +800°F.

Stringent Quality Assurance
and Engineering Standards are
rigidly enforced in all phases of
the manufacturing process.
This assures integrity of your
product design.

Heli-Coil inserts are available
mounted on plastic strips and wound
onto reels (500 or 1000 inserts
per reel). With power installation
tooling, use of strip feed inserts will

tests conducted by American
industry’s leading companies as
well as the U.S. Military. Successful
applications in the fields of aviation,

This choice of insert length balances
the bolt tensile strength against the
shear strength of the parent material.
This allows for the design of assemblies
where the bolt will fail before the parent
material. Tables III and IV below show
the length of insert to be used with
different combinations of bolts and
parent materials.

Corrosion Protection Methods
iÌ`Ê£ÊqÊ*>ÀiÌÊ>ÌiÀ>Ê*ÀÌiVÌ
1 1\ For oxide coating use Alodine, Anodize, Iridite, Hard Coat or equivalent.
Iridite 14 or 14-2 (MIL-C-5541) is recommended for critical parts rather than anodizing
(MIL-S-5002).
-1: For oxide coating use Iridite 15 or dichromate surface treatments. For
HAE finishes, always plug tapped holes first.

(MIL-L 46010) (no graphite).
iÌ`ÊÎÊqÊUtilize Heli-Coil Primer-Free II coated inserts or separate the parent material
from the insert by using liquid zinc chromate primer, Federal Specification TT-P-1757.
Apply the primer to the hole sparingly and install the insert while the primer is still wet.
In addition to the above methods, further corrosion protection can be achieved by:
1. Using blind holes wherever possible.
2. Using a sealing, insulating or step-down (5052 Alum.) washer under the head of the bolt.
3. Using bolts that extend completely through the length of the insert.
4. In critical applications, using a non-hardening sealer or compound on the
threaded assembly.

1.When the parent material shear
strength falls between two listed
values, use the lower of the two
values.
2.Parent material shear strengths
are for room temperature. For
applications at elevated tempera
tures, the shear strength of the
material at that temperature
must be determined for proper
selection of bolt and insert length.
3.Be sure that the engaged thread
length of the bolt is at least as long
as the full tapped thread depth
for the size selected (Dimension
“H”, Tables VII & VIII, pages 20 & 21).

The effect of corrosion on threaded
assemblies is dependent on many
factors — environment, types of
metals used, sealing mechanisms
and length of service. The following
recommendations apply for
minimizing the effects of corrosion
on Heli-Coil stainless steel insert
assemblies at operating temperatures
less than 800°F, using carbon steel
or alloy steel bolts.

Heli-Coil® Ê>ÃÃiLÞÊìÃ}
Boss Dimensions
Bolt Projection
Material Thickness
Standard boss configurations may
be used with Heli-Coil inserts.
The bolt must engage the
entire insert to insure maximum
strength of a Heli-Coil insert
assembly. It is strongly
recommended that the tang
always be removed and bolt
projection be equal to the full
tapped thread depth (Dimension
H, Tables VII & VIII, Pages 20 &
21). If design limitations prohibit
this, contact us to obtain
minimum bolt projection data.
The Õ material thickness
for through hole assemblies is
equal to the Insert Nominal Length
(Dimension Q, Pages 12 &13), without
a countersink and the insert installed
£É{£ÉÓÊ
pitch
below the
surface.
For
production,
Q
the hole
should be
countersunk, and
the insert
ÃÌ>i`ÊÎÉ{q££ÉÓÊ«ÌVÊLiÜÊÌiÊ
surface. In this case the minimum
material thickness is “Q” + 1 pitch.
A boss diameter of twice the nominal
bolt size is adequate for most load
conditions. For critical applications,
the boss diameter should be twice
the Heli-Coil tap major diameter
(Tables VII & VIII, Pages 20 & 21).
Boss thickness is a function of the
size and length of the insert chosen
and the particular requirements
of the component being designed.
The use of Heli-Coil inserts
generally minimizes the size of the
boss because their high strength
characteristics allow for smaller or
fewer fasteners.
Class of Fit
Since Heli-Coil inserts are flexible,
the class of fit of the final assembly
is a function of the tapped hole.
Heli-Coil STI (Screw Thread Insert)
taps are available in inch series for
both Class 2B and 3B. Metric Classes
include 5H and 4H5H. Class 2B or
5H tapped holes provide widest
production tolerances while Class
3B or 4H5H holes provide slightly
tighter tolerances.

2. Countersinking
Conventional machining methods are
used for Heli-Coil assemblies. The
process is simple…
£°ÊÊÀ
Ó°ÊÊ
ÕÌiÀÃ
Î°ÊÊ/>«
{°ÊÊ>}i
Countersinking the drilled hole
is recommended to prevent a feather
edge at the top of the tapped hole
and to help guide the insert into the
tapped threads. A 120° included
angle countersink is necessary to
insure that the angle of the tapped
thread and the countersink are the
Ã>iÊ£ÓäcÊeÊÓÊrÊÈäcÊÌ>««i`ÊÌÀi>`®°
1. Drilling
The suggested drill sizes listed for
aluminum in Tables V & VI, pages 18
& 19, are within the minor diameter
limits specified in NASM33537 or
MA1567. Drill sizes listed for steel,
magnesium and plastic are larger
(in most cases) allowing for parent
material “close-in” in soft materials
and increased tap wear life in hard
materials.
The drill depths listed in this table
allow for tap end clearance,
maximum insert “set-down”,
countersink, and the chamfer on the
tap. These drill depths are minimum
and should be increased where
possible, especially when using
Spiral Pointed Taps, to allow for chip
clearance. The formula for the drill
depth is given on Pages 18 & 19.
3. Tapping
The dimensions for the depth of the
full tapped thread (Dimension H,
Tables VII & VIII, Pages 20 & 21)
are MINIMUM for blind holes with
countersinks. For through holes
without a countersink the minimum
full tapped thread depth must be
equal to the insert nominal length
(Dimension Q, Pages 12 & 13).
Heli-Coil taps for free machining
materials are listed in Tables IX & XII,
Pages 20 & 23 Class 2B (inch),
5H metric and 3B (inch) or 4H5H
(metric) tapped holes. (Class of fit
recommendations are given on Page
14). There are four types of taps listed:
UÊ -ÌÀ>}Ì]ÊÕÌi]Ê*Õ}ÊEÊÌÌ}
style which are used for
hand and short run production
UÊ -«À>Ê*ÌÊ*Õ}taps (chips are
pushed forward) are used for
through holes and blind hole
with ample chip clearance at
the bottom.
UÊ }Ê-«À>ÊÕÌiÊÌÌ}Ê taps (chips are pulled out of the
hole) are used for deep or blind
holes in soft stringy materials
and holes with minimal chip
clearance
UÊ ,Õ}}Ì>«ÃÊÇÉ£È£¸®Ê>ÀiÊÊ Ê
available for materials difficult
to tap to reduce the load and
wear on the finishing tap.
If it is necessary to decrease the

tapped hole, one or more of the
following steps may be helpful:

4. Gaging
Heli-Coil thread plug gages should be
used to check, according to sampling
plan, the tapped holes before insert
installation. See Pages 24 & 25 for gage
part numbers and further gaging data.

Heli-Coil® ÊÌ>««}Ê`>Ì>ÊqÊiÌÀV
Heli-Coil taps in various types and
styles produce holes for Tolerance
Classes 4H5H or 3B and 5H or 2B
for use in the general range of
aluminums, magnesiums, mild steels,
free machining stainless steels and
other free machining materials.
Conventional shop practice and
production procedures, speeds,
feeds and lubricants should be
used in combination with proper
fixturing and good tapping machines
or tapping heads. The tapped hole
must be held within the stated pitch
diameter limits for the required
Tolerance Class of fit for the installed
Heli-Coil insert. For Standard (free
running inserts), a tolerance class 5H
or 2B is recommended. For ScrewLock inserts, a tolerance class 4H5H
or 3B is recommended in order to
develop higher locking torques.

After the insert is installed, the "
thread plug gage may not enter
freely; however, the insert will
always seat itself when the bolt or
screw is installed and tightened.
(Reference MA1567)
When gaging tapped holes which
have been thoroughly cleaned
or which have a protective finish
applied, the gage should always be
lubricated with light oil.
The thread plug gage may enter
provided that a definite drag results
on or before the second turn of entry.
(Reference ANSI B1.16)

Heli-Coil® ÊÌ}
Hand Inserting Tools
Types of Tools
Tool Service
The various tools to install HeliCoil inserts are presented on the
following pages.
All Heli-Coil tooling is backed by our
extensive expertise and experience
in virtually any application. Of
course, all tools are fully warranteed.
In addition, our Application
Engineering Department is always
available to assist in installation
techniques, special tooling (longer
or shorter length tools, etc.)
and tool service. For very high
production, Heli-Coil will provide
for the successful development of
automated installation systems.
For production runs, prototype work,
salvage, and repair, hand inserting
tools are available. For high volume
production, power inserting tools are
also available. Both types of tools
are dimensioned (pages 29 and 31) to
aid determination of accessibility to
the tapped hole.
Both hand and power inserting tools
feature a threaded mandrel which
engages the insert and provides a
positive lead to guide the insert into
the tapped hole easily and quickly.
Power inserting tools consist of an
air motor, adapter and front end
assembly. The front end assembly
consists of a prewinder, mandrel
and 3 spacers (1 for each length of
insert to be installed). The versatility
and adaptability of Heli-Coil power
inserting tools is shown on page 32.
The tool can be hand held, vertically
or horizontally mounted, and adapted
to both semi-automatic and fully
automatic installation stations. HeliCoil power inserting tools can be
adapted to assembly stations, rotary
tables and transfer lines.

Pictured above are the various
designs of Heli-Coil hand inserting
tools. Generally, finer pitch inserts
are proportionately larger in the
free state than coarse pitch inserts
and thus have to be “pre-wound” to
a smaller diameter for installation.

Heli-Coil® Ê«ÜiÀÊÃiÀÌ}ÊÌÃ
Power Tool Holder
Electronic Power
Inserting Tool
Heli-Coil offers an electronic
power tool where electric power
is preferred over air. The slender
configuration of the mandrels
allows them to reach into
constricted areas. Electric power
meets the requirements of clean
room operations. Operators prefer
electric power because it is quieter.
The electronic tool is lighter to
minimize operator fatigue. Mandrel
assemblies are available to install
the sizes of Heli-Coil bulk loaded
inserts listed below.
Application Note: Variations in
Mandrel Assembly dimensions
and threads are available on
special order to meet individual
applications. For Mandrel
Assemblies to meet your special
conditions, please contact
Heli-Coil Applications Engineering
Department at (203) 830-3274.
The Power Tool Holder 23537
is mounted on a bench and the
appropriate air motor is attached to
a spring loaded air tube at the end of
a movable arm. A mounting arm is
also provided for attaching reels
of strip-feed inserts.
Pneumatic Power Tool
Installation Kit
This Heli-Coil power tool installation
kit (8522) contains an Air Motor
(8510-1), adapter, tools, a filterregulator-lubricator, oil, two quick
disconnect fittings, and wrenches.
All are packed in a portable molded
box with easy-to-follow operating
instructions. Front End Assemblies
may be ordered separately to fit
the sizes of Heli-Coil inserts to be
installed.

Extracting Tools
Occasionally Heli-Coil inserts
must be removed. Inserts may
be removed manually with
little effort. This is done by
inserting the blade of the
extracting tool into the HeliCoil insert so that the V
section of the blade is
toward the top end of
the insert. Strike the head of the
tool with a light blow. Maintaining
a steady pressure of blade against
insert, turn the extracting tool
counterclockwise until the insert
is removed.
